Title: Hydrostatic drive system
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F04B49/00
Filed: 1981-02-28
Abstract: A hydrostatic drive system has hydrostatic work-performing machines with a variable intake or delivery volume which are coupled to small hydrostatic machines acting as a pump or motor as signal transmitters for the emission of a signal, determined by the rotational speed of the hydrostatic work-performing machines, for the device which adjusts the said work-performing machines. Via a metering unit, one of the two cylinder spaces of the actuating cylinder of the adjusting device is supplied with a flow of control oil which determines the setpoint value of the rotational speed of the associated hydrostatic work-performing machine. To increase the accuracy and responsiveness of rotational-speed control and at the same time improve the efficiency of the hydrostatic drive system, the metering unit, which is designed as an adjustable restrictor or flow regulator, is placed in the return of the flow of control oil. A controllable parallel flow can be taken past the signal transmitter and this can be used as an additional means of determining the rotational speed of the hydrostatic drive. In the case of an actuating cylinder with a continuous piston rod, the piston rod is subjected to an additional load in one direction of displacement or the other in accordance with the desired direction of rotation so as to determine the direction of rotation of the hydrostatic work-performing machine.

Patent DE-3147802-A1 (DE)
Title: Water-tube boiler
Inventor: WIESER RUDOLF DR
IPC: F23C6/00
Filed: 1981-12-03
Abstract: The invention relates to a water-tube boiler, the firing of which is converted from oil or gas to coal dust. The main aim of the invention is that the nominal steam generating capacity of the boiler and the steam states (pressure, superheating temperature) at the boiler outlet are the same after the conversion as before the firing conversion. In order to take into account the requirements for lower combustion chamber loading and reduced flue gas speed in the contact heating surfaces, and in order to allow for the greater flue gas quantity in the case of coal dust firing, the original oil or gas-fired water-tube boiler is equipped with one or more precombustion chambers and one or more downstream heating surface blocks. Moreover, to reduce fly ash accumulation in the combustion chamber, a deflector plate for the flames is arranged in it and tertiary air nozzles are arranged at the combustion chamber front wall. The firing conversion proposed here can be carried out with careful planning and preparation on medium-sized boilers during a summer period. <IMAGE>

Title: Closure for an ice-cream container
Inventor: MCLAREN EDWIN C
IPC: B65D43/02
Filed: 1981-12-15
Abstract: A closure for a cylindrically shaped ice-cream container or the like has an integral lid of circular shape made of plastic with a rim hanging down. The top of the lid is provided with a concentric bead projecting upwards and inwards which is tapered inwards on its outer surface in such a way that it enhances the retention of a multiplicity of similar lids in a stacked state. The bead strengthens the lid, enhances the nested stacking of containers with fitted lids and provides a locking and protective recess for printed labels. The rim of the lid has a lower inner surface part which is tapered outwards and matches the outside surface of the bead in order to facilitate the nested stacking of the lids and to allow the lid to be gripped and readily removed from a firmly fitting engagement with an ice-cream container. An upper inner region of the lid rim recessed in an annular manner allows the ice-cream container to expand without the lid springing off the container. The plastic injection point is countersunk in the surface of the lid in order to protect the label and the bottom of a stacked container. <IMAGE>

Title: Fuel injection device
Inventor: EISELE HERMANN DIPL ING DR
IPC: F02M59/36
Filed: 1981-12-21
Abstract: A fuel injection device is proposed on which a cam disc (15) in a pump chamber (10) is provided for the actuation of a pump piston (14) for fuel metering. At the same time the cam disc (15) can be adjusted by means of an injection adjusting piston (20), which is acted upon by a pressure (P2) derived from the pressure (P1) prevailing in the pump chamber, in such a way that the start of fuel delivery is varied. A valve which can be actuated as a function of an electronic control instrument (19) at the same time serves to adjust the pressure (P2) acting on the injection adjustment piston (20). The valve is designed as a baffle plate valve (25) on which the pressure coming from the pump chamber (10) is fed by way of a baffle plate (28) to the injection adjustment piston (20) in such a way that pressure peaks on the injection adjustment piston (20), which are caused by the reaction of the pressure stroke on the cam disc (15), lead to closure of the baffle plate. In this way the flexibility of the injection adjustment piston and hence the scatter in the fuel metering quantity is reduced. <IMAGE>
